1. The SPE first sends a message to the on-board microprocessor to loop
around both the information and control channels for the port. Then, the
primary information channel loop back test is run. The test is performed by
sending a digital count from the Tone-Clock circuit pack on the primary
channel time slot and receiving the same digital count with a GPTD. The
digital count looks like transparent data to the on-board microprocessor.
2. With the port still in loop around mode, the S channel Loop Around Test is
performed next. This test consists of sending four different transparent
patterns to the on-board microprocessor, receiving them back, and
comparing them.
3. The third test is a Loop Around Test for the secondary (alternate) channel.
It is not performed for data modules since this channel is not used by
MPDMs, MTDMs, and stand-alone DA’s [G3iV2-386].
4. A Conference Test is done next for the primary channel. This test is the
same as the Analog Line Terminal/Port Conference Test (#6).
Only one value (Pass, Fail, or Abort) is generated as a result of four tests run. If
any test fails or aborts, the sequence is stopped.

ABORT Internal System Error.
1. Retry the command at one-minute intervals a maximum
of 5 times.
1000 ABORT System resources required to run test are not available. Port
may be busy with a valid call. Use display port PCSSpp
command to determine the data module extension. Then use
status data module command with the extension number to
determine the service state of the data module. If the service
state indicates that the data module is in use, then port is
unavailable for certain tests. Wait until port is idle before
retesting.
1. If the port status is idle, retry the command at one-minute
intervals a maximum of 5 times.
1001 ABORT System resources required to run this test are not available.
1. Retry the command at one-minute intervals a maximum
of 5 times.
